(Oman press machine hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）
press machine hydraulic cylinder are widely used in Oman，because of no need for deceleration device，long service life，smooth movement.So our company has designed press machine hydraulic cylinder for customers from Oman.
The piston rod of the press machine hydraulic cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.
press machine hydraulic cylinder installation precautions: Before installing the press machine hydraulic cylinder into the system, the parameters on the press machine hydraulic cylinder label should be compared with the parameters when ordering. The base of the press machine hydraulic cylinder must have sufficient stiffness, otherwise the press machine hydraulic cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.
The pressure of the sliding surface of the press machine hydraulic cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the press machine hydraulic cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.
In the case of serious wear on the inner surface of the press machine hydraulic cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the press machine hydraulic cylinder manufacturing process for replacement. The press machine hydraulic cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.
What is the pressure provided for a 63-bore cylinder with a pressure of 2 mpa?
2 mpa pressure is equivalent to 20 kg per square centimeter, 6.3 cm straight longitude, 3.15 cm radius, square, multiplied by, calculated an area of about 31.5 square centimeters, multiplied by 20 kg, the pressure is about 630 kg.
How to deal with hydraulic cylinder inner wall rag, local wear serious or corrosion?
It can be reparied if the inner wall of the hydraulic cylinder is frayed, local wear or corrosion. We can use the inner wall cold melting copper technology, it has the following advantages: first, the temperature is low, the operating temperature is less than 180 degrees, and the heat affected zone is small. Second: high hardness is up to Brinell hardness 280, wear resistance and anti-corrosion. Third: the process is mature, some large coal mills have been repaired with this method and the effect is remarkable.
